通过乳液共聚合分别合成了两种具有互补结构的共聚物乳液 :聚 (甲基丙烯酸甲酯 -丙烯酸丁酯 -甲基丙烯酸 ) [P(MMA- BA- MAA) ]和聚 (甲基丙烯酸甲酯 -丙烯酸丁酯 -乙烯基吡咯烷酮 ) [P(MMA-BA- VP) ]。通过 1H- NMR测定 ,研究了共聚物组成与单体投料组成的关系 ;通过 FR- IR、DSC、表面能及力学性能测试 ,研究了 P(MMA- BA- MAA) / P(MMA- BA- VP)共聚物复合体系氢键相互作用及其对聚合物性能的影响。结果表明 ,P(MMA- BA- MAA) / P(MMA- BA- VP)共聚物复合体系存在氢键相互作用 ,氢键相互作用导致复合体系表面能降低、拉伸强度提高
Two copolymer emulsions with complementary structures were synthesized by emulsion copolymerization: poly (methyl methacrylate-butyl acrylate-methacrylic acid) [P (MMA-BA-MAA)] and poly (methyl methacrylate Ester-butyl acrylate-vinylpyrrolidone) [P (MMA-BA-VP)]. The relationship between the copolymer composition and monomer composition was studied by1H-NMR. The properties of P (MMA-BA-MAA) / P (MMA-BA- VP) Copolymer Composite System and Its Effect on the Properties of Polymers. The results show that the hydrogen bond interaction exists between the P (MMA-BA-MAA) / P (MMA-BA-VP) copolymer system and the hydrogen bond interaction leads to the decrease of the surface energy and the increase of tensile strength
